Detailed Description

Declare variables for reading or writing BUFR messages via a C language interface.

These variables are used by the C language interface which encompasses functions openrb(), openwb(), openab(), backbufr(), cewind(), closfb(), crdbufr() and cwrbufr().

When allocated, these variables are dimensioned as one larger than NFILES because of the difference in array indexing between Fortran and C. In each function, the value passed in for nfile will be a Fortran file ID ranging in value from 1 to NFILES, so we need to allow for this same range of values in C, which would otherwise expect the array indices to range from 0 to NFILES-1.
